Photo: Far-Flung Crash May Have Created Dino-Killer Asteroid

The collision of two giant asteroids (as seen in this artist's illustration, top) may have peppered the inner solar system with hundreds of thousands of boulders, according to a new study.

Those fragments likely included the rock that created the moon's Tycho Crater (bottom left) and the K-T impactor asteroid, which is believed to have wiped out the dinosaurs by crashing into what is now Mexico (bottom right), scientists say.
